About

Backend/data engineer who helped evolve Bitnimbus LLC’s Kafka-as-a-service MVP from a monolith into an event-driven distributed system, using careful design, parallel rollouts, and idempotent event handling to maintain correctness. Also built production-grade API and database security (JWT scopes, rate limiting, explicit Postgres policies/RLS-style controls) and improved Prometheus monitoring by eliminating false outages via heartbeat metrics and windowed aggregation.

Key Strengths

  • Led monolith-to-distributed redesign for Kafka-as-a-service platform
  • Strong upfront architecture/design planning before implementation
  • Risk-managed migrations using strangler pattern and parallel event consumption in production
  • Designs for data integrity in distributed systems (idempotency, unique keys, state ownership)
  • API security and scalability improvements (JWT scopes in middleware, rate limiting to curb expensive polling)
  • Fine-grained database security (explicit table policies, custom JWT claims, functions/RPCs for sensitive data)
  • Improved monitoring robustness by distinguishing 'no data' vs 'unhealthy data' with heartbeat metrics and tolerant aggregation
